Other claims from this paper (6)
- Method / resource Removal sampling consistently underestimated larval coccinellid density.
- Association Timed counts correlated significantly with absolute adult and larval coccinellid densities.
- Association Sweepnet samples correlated significantly with absolute adult and larval coccinellid densities.
- Method / resource Models converting relative to absolute density had R2 values of 0.89 to 0.93.
- Method / resource Sweepnet sampling was more precise per effort than timed count, quadrat and removal sampling for adult density.
- Method / resource Removal sampling was the least efficient method.
